COLOSSUS CHESS 3.0 is the best chess program for ATARI computers. It was written using the very latest techniques by Martin Bryant, a computer chess programmer with over seven years experience. It has been tested against a wide range of other programs and is stronger than any other chess program for the ATARI range of computers, plus most of those available for other computers.
It has the widest range of true features available, including some never before implemented in any home computer chess program.
COLOSSUS CHESS 3.0 also has a perfect understanding of all the rules of chess, including under-promotions, the fifty move rule and all draws by repetition. It also handles all the standard mates, including King and two Bishops versus King and the very difficult King, Bishop and Knight versus King.
